Architecture, Building and Structure Design The Tree Residential House by Adel Badrawy This house is a prototype for a residential complex aimed to accommodate young families. It is designed to symbolize the tree. A tree that grows and continues to spread its roots down the earth and its branches up in the air. It's the symbol of a family. It's obvious that this house structure is growing the same as the tree structure. The stem of the tree is the core of the house which in this case is the stairs. The stairs that shape its journey. A journey from the bottom the entrance level to the top the roof garden. With all spaces cantilevered out of the core.
